UNITED STATES PATENT OFFICE.

I JOEL HAYDEN, JR., OF BOSTON, MASSACHUSETTS, ASSIGNOR, BY MESNE ASSIGNMENTS, TO HAYDEN MACHINERY COMPANY, A CORPORATION OF MAINE.

Specification of Letters Patent.

Patented March 13, 1906.

Application filed December 28, 1904:. Serial N0. 238,635.

To all whom it may concern:

Be it known that I, JOEL HAYDEN, Jr., a citizen of the United States, residing in Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Ring Spinning and Twisting Apparatus, of which the following is a specification.

This invention relates to that class of ring spinning. and twisting apparatus in which the ring is nonrotativethat is, while it may have some slight horizontal or approximately rotative movement such movement does not entitle it to be termed a rotary ring, as there is no continuous movement and of course no complete rotation. The ring belongs, therefore, to the class usually termed stationary rings.

This invention has for its principal object to prevent the wearing of the lower flange on the ring, such wear being commonly produced by the vibration of the ring and its direct contact with the supporting plate or holder, and to obviate the necessity for mutilating the ring in order to engage it by means of clips or similar devices extending from the supporting-plate by introducing between the spinning-ring and the supporting-plate an intermediate member which is adapted not only to be sprung or snapped over the lower flange of the ring, but to accommodate itself to rings of different sizes and to provide means whereby a suitable instrument, such as a knife-blade, can be used to separate the ring from the intermediate member by springing or prying it out of engagement therewith or to spread the intermediate ring'for the purpose of inserting the spinning-ring.

The nature of the invention is fully described below and illustrated in the accompanying drawings, in which Figure 1 is a plan view of a spinning-ring,

. the supporting plate or holder, and my improved intermediate member assembled and in position on the ring-rail and embodying my invention. Fig. 2 is a similar view with the spinning-ring removed. Fig. 3 is a vertical section taken on line 3 3, Fig. 1. Fig. 4 is a vertical section taken on line 4 4, Fig. 1.

Similar letters of reference indicate corresponding parts.

The spinning-ring a is constructed in the ordinary manner and provided with the upper and lower flanges b and c.

(i represents the supporting plate or holder, and e the ring-rail.

Intermediate of the supporting plate or holder and the spinning-ring is a curved or C-shaped spring member 9, whose ends g face each other, as shown in Fig. 2, but do not quite meet, the said member constituting a split ring. This member is formed on its inner edge with a flat horizontal ledge f, upon which the spinning-ring is adapted to rest, and is provided with the upwardly and inwardly extending annular lip h, which is adapted to be sprung over the edge of the flange of the spinning-ring, and thereby retain said ring permanently in position. More over, this member, which is preferably thick and heavy, is provided with radial passages it, into which the clips m, which are integral with and bent upward or inward from the plate (1, are adapted to extend, thereby holding the intermediate member and supportingplate in engagement.

To assemble the parts, the clips m are sprung over the edges Z into the passages 7c, and the spring member 9 is forced over the edge of one of the flanges of the spinning-ring, ,said member yielding and having its ends g forced apart to a greater or less extent, according to the size of the spinning-ring or its flange, and then overlapping and holding said flange by means of the lip h.

It is desirable that there should be some provision whereby the end of a thin instrument, such as a knife-blade, can be used to spread the intermediate member when the spinning-ring is to be inserted and to assist in prying the spinning-ring out of engagement therewith. I have provided, therefore, vertical and horizontal recesses or notches p and s. The recess or notch p is formed vertically in the lip h, as shown in Figs. 1, 2, and 3, and extends practically through said lip horizontally down to about the level of the ledge When the spinning-rin is to be applied, a blade is inserted vertica ly in this recess and the flange of the ring pushed down into position. The recess or notch s is formed horizontally in the body of the member g, as illustrated in Figs. 1, 2, and 4, and

extends below the level of the ledge f and under the ring. To pry the spinning-ring out of engagement, an instrument is inserted l1ori, zontally in this recess under the flange of the rm I Iaving thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. In an apparatus of the character de scribed, the spinning ring, the supporting plate or holder, a permanent sprin member of the shape of a split ring intermedlate of the spinning-ring and the supporting plate or holder and rigid with the spinning-ring and resting wholly on the horizontal surface of the plate or holder, and means for connecting said plate or holder and intermediate spring member whereby said member is allowed to move'horizontally on the surface of said plate or holder but prevented from continuous rotative movement.

2. In an apparatus of the character described, the spinning ring, the supporting plate or holder, a permanent spring member of the shape of a split ring intermediate of the spinning-ring and the supporting plate or holder and rigid with the spinning-ring and resting wholly on the horizontal surface of the plate or holder, and means for connecting said plate or holder and intermediate spring member whereby said member is allowed to move horizontally on the surface of said plate or holder and is in contact therewith during the entire horizontal movement.

3. In an. apparatus of the character described, the spinning-ring, the supporting plate or holder having a flat horizontal upper surface, a permanent weighted spring member of the shape of a split ring intermediate of'the spinning ring and supporting plate or holder and rigid with the spinningring and resting on the horizontal surface of the plate or holder, and means for connecting said plate or holder and intermediate member whereby said intermediate member is allowed curved horizontal movement on lines ring and the supporting plate or holder, of a member intermediate of the plate or holder and the spinning-ring and adapted to be spread or sprung over a flange of the ring, said intermediate member being provided with recesses or notches adapted to receive an instrument whereby the ring may be assisted into or out of engagement with said intermediate member.

5. In an apparatus of the character described, the combination with the spinningring and the supporting plate or holder, of a member intermediate of the plate or holder and the spinning-ring and adapted to be spread or sprung over a flange of the ring, said intermediate member being provided with a substantially horizontal recess or notch extending under the flange of the ring when it is in engagement with said member for the purpose set forth.

6. In an apparatus of the character described,-the combination with the spinningring and the supporting plate or holder, of a member intermediate of the plate or holder and the spinning-ring and adapted to be spread or sprung over aflange of the ring, said intermediate member being provided with a substantially vertical recess or notch extending down outside the flange of the ring when it is in engagement with said member, for the purpose set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
